A cheetah reaches a final velocity of 39.4 ft/sec in 1.25 seconds. If it accelerated at a rate of 2.10 ft/sec2, what was its initial velocity, and how far did it travel in this time?

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
